Sonography could replace biopsy in some breast tumors
Ultrasound is an acceptable alternative to biopsy for the management of tumors hidden to x-ray mammography but diagnosed as probably benign under the ultrasound Breast Imaging Reporting and Data System, according to a study in the July issue of Radiology.
Ultrasound is an acceptable alternative to biopsy for the management of tumors hidden to x-ray mammography but diagnosed as probably benign under the ultrasound Breast Imaging Reporting and Data System, according to a study in the July issue of Radiology.
Investigators at the Ambulatory Care Center in Steyr, Austria, retrospectively evaluated 445 nonpalpable solid masses from 409 women who underwent ultrasound between January 2001 and December 2003. These masses were partially or completely obscured by dense breast tissue on mammography but were classified as probably benign by ultrasound. Of the 445 masses, 442 remained stable during a mean follow-up of more than three years. The false-negative rate and negative predictive value of the test were 0.2% and 99.8%, respectively.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
